(NEXSTAR) – Officials in Costa Rica are reportedly walking back their previous suggestion that Miller Gardner, the 14-year-old son of former Yankees outfielder Brett Gardner, died of asphyxiation after “food intoxication” during the family’s recent trip to the country. Investigators initi ally believed the teen may have died of asphyxiation, an official with Costa Rica’s Judicial Investigation Agency said Monday, according to reports from ABC News and NBC News. An official speaking with CNN pointed to vomit being found with the boy as a potential determining factor. However, on Tuesday, officials ruled out asphyxiation as the cause of Miller Gardner's death, ABC News and People reported. Costa Rican National Police said the teen's respiratory tract was clear and noted that additional tests were being done. It could take two to three months for those tests to be completed. Food poisoning may still be connected to his death, authorities have indicated. Miller died “peacefully” in his sleep, his family said Sunday. Authorities do not believe his death is suspicious, according to reports. A representative for the Costa Rican agency did not immediately respond to a request for comment.

He lived life to the fullest every single day.” The Gardners, who share another son, Hunter, asked for privacy as they “mourn and search for healing,” and did not provide any additional details.
